Other Projects

Here are some other projects that are a lot of fun.  Both of these marble tracks are built out of different thicknesses of baltic birch plywood and use one inch diameter marbles.




The first track is one that goes completely around my youngest son's room.  It's easier to watch the video than explain it, so give it a look.

Both the circle lifter and the step lifter are run by small gear motors that run off rechargeable "AA" batteries.




 





My oldest son has this marble track in his room.  It goes without saying that this one will be much easier to move when the time comes.


This track was much harder to build with the sharp curves.
